Title:
SPECTRAL IMAGING DEVICE ADJUSTMENT METHOD AND SPECTRAL IMAGING SYSTEM
Document Type and Number:
WIPO Patent Application WO/2013/176204
Kind Code:
A1
Abstract:
Provided is a spectral imaging device adjustment method capable of easily adjusting a relative placement relationship among parts in a spectral imaging device. The spectral imaging device (30) is provided with: a collimator lens (32), a diffraction grating (33), a condensing lens (34), an array-type light-receiving section (35) and an adjustment means that adjusts the relative placement relationship among these parts. The relative placement relationship among the parts is adjusted such that an etalon filter is placed on the optical path of light input to the collimator lens (32), and the condensing point of each wavelength of light condensed by the condensing lens (34) is positioned on a specified line of the array-type light-receiving section (35).
